Surviving SD60s

In 1985 Conrail bought the three EMD demonstrators from EMD, and later went back to the well 4 years later, in 1989, for another 25 standard cab units. The demonstrators were numbered 6840, 6841, and 6842, while the later order was numbered from 6843 through 6867.

In 1999, the fleet was divided between Norfolk Southern and CSX. Those assigned to NS were renumbered into the 6701 - 6716 series, while CSX allocated units became 8710 - 8721.
